A company has an RPO of 4 hours for a Cloud SQL database. What backup strategy satisfies this requirement at minimum cost?
Answer: Automated backups every 4 hours with point-in-time recovery enabled
Automated backups every 4 hours combined with point-in-time recovery ensures data loss is limited to at most 4 hours, meeting the RPO requirement.
Which GKE feature helps ensure a minimum number of pods remain available during voluntary disruptions like node upgrades?
Answer: Pod Disruption Budget (PDB)
Pod Disruption Budgets define the minimum number of pods that must remain available during voluntary disruptions, preventing outages during maintenance.
What is the purpose of health checks in a GCP Managed Instance Group?
Answer: Automatically detect and replace unhealthy VM instances (autohealing)
MIG autohealing uses health checks to detect unhealthy instances and automatically recreate them, maintaining the desired instance count and availability.
A GCP architect is designing a system where a Cloud Run service must continue operating even if a GCP region goes down. What is the recommended approach?
Answer: Deploy Cloud Run services in multiple regions behind a Global Load Balancer
Deploying Cloud Run services across multiple regions with a Global Load Balancer ensures regional failover and continuous availability during outages.
Which disaster recovery pattern offers the lowest RTO but highest cost in GCP?
Answer: Hot Standby (Multi-Site Active-Active)
Hot Standby / Multi-Site Active-Active keeps identical production environments running in all regions simultaneously, enabling near-zero RTO at maximum cost.
An organization wants to test their GCP disaster recovery plan without causing a production outage. Which approach is best?
Answer: Conduct a chaos engineering or DR simulation in a non-production environment
DR simulations and chaos engineering tests in non-production environments validate recovery procedures without risking production availability.
